### How to save a binary file?

```java
final String link =
    "https://repo1.maven.org/maven2" +
    "/org/jodd/jodd-http/3.9.1/jodd-http-3.9.1.jar";

HttpResponse response = HttpRequest
    .get(link)
    .send();

byte[] bytes = response.bodyBytes();

FileUtil.writeBytes(
    new File(SystemUtil.userHome(), "jodd-http.jar"), bytes);
```

### How to follow multi redirects?

Either use `HttpBrowser`:

```java
HttpBrowser browser = new HttpBrowser();

browser.sendRequest(HttpRequest.get("google.com"));

// read response
Response response = browser.getResponse();
String page = browser.getPage();
```

or the flag `followRedirects()` to enable the following redirects:

```java
HttpResponse response =
    HttpRequest
        .get("google.com")
        .followRedirects(true)
        .send();
```

### What is the difference between HttpRequest and HttpBrowser?

`HttpRequest` represents just a single request; clean and simple.

`HttpBrowser` emulates browsing of a website (i.e. set of URLs) like a browser. Besides sending requests, it also stores and resends cookies, maintaining the current user session. Moreover, the `HttpBrowser` uses new request on redirection following, allows common request headers for all the requests etc.

### Server choses TLSv1.2, but that protocol version is not enabled?

Just add the following property `-Dhttps.protocols=TLSv1.1,TLSv1.2` which configures the JVM to specify which TLS protocol version should be used during HTTPS connections.

Since 8u292, JDK 11.0.11, JDK16+ Java requires use of TLS v1.2 or v1.3.
